Abstract
Description
Die vorliegende Erfindung betrifft eine Vorrichtung zum Spreizen der Dornfortsätze zweier aufeinanderfolgender Wirbel. Dabei liegen die Dornfortsätze auf stufenlos aufweitbaren Spreizmitteln. Beide Spreizmittel sind an einem Grundkörper angebracht, der stufenlos aufgeweitet werden kann und wobei das Ausmaß der Ausweitung den Abstand der Spreizmittel und dadurch den Grad der Spreizung der Dornfortsätze zueinander bestimmt.The The present invention relates to a device for spreading the Spinous two successive whirls. In this case, the spinous processes are on infinitely expandable expansion means. Both spreading agents are on a basic body attached, which can be infinitely widened and wherein the Extent of Extending the distance of the spreading means and thereby the degree of Spread of spinous processes determined to each other.
Im Stand der Technik sind nur Ausführungsformen zum Spreizen von Dornforfsätzen bekannt, welche keine stufenlose Aufweitung bzw. Spreizung der Dornfortsätze zweier benachbarter Wirbel zulassen. Die Spreizung wird durch Abstandshalter definierter Höhe bewerkstelligt.in the Prior art are only embodiments for spreading spine implants known which no continuous expansion or spreading of the spinous processes of two allow adjacent vortex. The spread is made by spacers defined height accomplished.
So offenbart US 2003/0065330 A1 eine Vorrichtung zum Spreizen der Dornfortsätze von Wirbeln, wobei auf einer horizontalen Schiene zwei vertikale Fixierungsmittel angebracht sind. Die Dornfortsätze der Wirbel liegen auf einem über die horizontale Schiene aufschiebbaren Abstandshalter auf, dessen Dicke das Maß der Aufspreizung bestimmt. Nach erfolgter Implantation ist der Grade der Aufspreizung nicht mehr veränderbar.So US 2003/0065330 A1 discloses a device for spreading the spinous processes of Whirling, being on a horizontal rail two vertical fixatives are attached. The spinous processes the whirls lie on one over the horizontal rail slidable spacer, whose Thickness the measure of Spreading determines. After implantation is the grade the spread no longer changeable.
Aufgabe der vorliegenden Erfindung ist die Bereitstellung einer Vorrichtung zum Spreizen der Dornfortsätze zweier aufeinanderfolgender Wirbel, welche es erlaubt, den Grad der Spreizung stufenlos während der Implantation einzustellen.task The present invention is the provision of a device for spreading the spinous processes two successive vertebrae, which allows the degree the spread stepless during to adjust the implantation.
Diese Aufgabe wird durch die Bereitstellung einer Vorrichtung gemäß Patentanspruch 1 gelöst. Weitere vorteilhafte Ausgestaltungen, Aspekte und Details der Erfindung ergeben sich aus den abhängigen Ansprüchen, der Beschreibung, den Beispielen und den Figuren.These The object is achieved by providing a device according to claim 1 solved. Further advantageous embodiments, aspects and details of the invention arise from the dependent ones claims, the description, the examples and the figures.

Durch diese harten Materialien wird gewährleistet, dass das Ausmaß der Aufweitung der Spreizmittel auch dem Ausmaß der Spreizung der Dornfortsätze entspricht. Demgegenüber würde ein elastisches Material durch den bei größerer Aufweitung überproportional ansteigenden Druck der Dornfortsätze stärker deformiert als bei einer geringeren Aufweitung, so dass kein linearer Zusammenhang zwischen dem Abstand der beiden Spreizmittel und dem Abstand der beiden Wirbelfortsätze zueinander bestehen würde. Es ist jedoch möglich, Materialien zum Einsatz kommen zu lassen, welche eine minimale Eigenflexibilität aufweisen, wie beispielsweise PEEK oder UHMWPE, um einen Knochenabbau im Bereich der Kontaktzonen zu vermeiden.By These hard materials will ensure that the extent of expansion the spreading means also the extent of Spread of spinous processes equivalent. In contrast, would be one elastic material disproportionately due to the larger expansion increasing pressure of spinous processes stronger deformed as at a smaller expansion, so no linear Relationship between the distance between the two spreading means and the distance of the two spinous processes would exist to each other. It is possible, however, To use materials which have minimal intrinsic flexibility, such as PEEK or UHMWPE, for bone resorption in the area of Avoid contact zones.

Beispiel 1example 1
Die Vorrichtung wird im Grundzustand befindlich implantiert, d.h. zwischen die beiden Dornfortsätze der zu spreizenden Wirbel gebracht, ohne dass eine Durchtrennung des Ligamentes supraspinosus erforderlich wäre, was einen großen Vorteil der erfindungsgemäßen Implantate darstellt. Nach dem Platzieren zwischen den Dornfortsätzen erfolgt die Aufweitung bzw. Expansion der Vorrichtung durch das Einschrauben der Gewindeschraube.The Device is implanted in the ground state, i. between the two spinous processes brought to the spreading vortex, without any transection of the supraspinosus ligament would be required, which is a big advantage the implants of the invention represents. After placement, take place between the spinous processes the expansion or expansion of the device by screwing the threaded screw.
